13.1 Introduction
Each of the optical filters available for use with the Monitor, has a
“UA” number printed on them. The “UA” numbers run from UA 0968
– UA 0989 and UA 0936. The Monitor has a carousel wheel on which
relevant optical filters are mounted. There are six mounting holes in
the carousel. Each mounting hole is labelled with one of the following
letters: “A”, “B”, “C”, “D”, “E” and “W” (see Fig.13.1). Before leaving
the factory a special “water” filter is mounted in the position marked
“W” and user-chosen optical filters are mounted in the other
positions of the carousel. If less than 6 optical filters are installed in
the carousel, blank plates are mounted in those positions of the
carousel where no optical filter has been installed.
